Toyota Prius

The Toyota Prius, models through 2010 - 2015 have a known issue with the Brake Booster (actuator) and ABS Pump where the parts will degrade and break at or around 100,000mi. Toyota issued a bulletin and had a replacement program that covered the part that has since elapsed but has not corrected the issue with existing stock and inventory so the problem remains. When I purchased my car I was the 2nd owner, the car was purchased with roughly 160,000mi. The previous owner had informed me that he…

On XXX, at approximately 152,570 miles, the brake, ABS, and traction-control warning lights illuminated at the same time on my 2013 Toyota Prius. The brakes felt spongy, and I heard a recurring buzzing sound approximately every 3 seconds. Because of the change in brake-pedal feel and concerns about braking safety, I stopped using the vehicle. I reported the problem to Longo Toyota in [XXX], which directed me to Toyota customer support. The vehicle was subsequently diagnosed with trouble code…

The windshield cracked due to fallen bricks from my house. I heard the noise of sudden…

My vehicle is experiencing the well-known brake booster failure. This started at 90,000 miles, with an increased frequency in the running of the brake booster. It has steadily gotten worse, and now the pump runs with every brake application or every 13 seconds. There is now a hissing sound when I apply the brakes. I have repeatedly taken this to Toyota dealers and have been told: The system is working as designed; no issues found. When I asked why the pump runs so frequently. No…

While driving our 2013 Toyota Prius, the vehicle experienced a sudden and severe loss of braking effectiveness while the vehicle was in motion. This created an immediate safety risk because the vehicle did not respond to braking as expected. After the incident, the vehicle displayed the red BRAKE warning light, ABS warning light, brake-system warning light, and an audible warning. The vehicle was not driven after the failure and was transported to a Toyota dealership for diagnosis. The dealer…

I turned on my car in a flat parking lot, reversed out of my spot, and drove up to a traffic light to exit the parking lot. When the light turned green, I took my foot off the brake and tried to accelerate, but nothing happened. After a few seconds, my car lurched forward with a sudden jerk, and I was able to exit, but this behavior (no movement, then sudden jerk) continued to happen. I was scared that I would get into an accident, so I pulled over and turned the car off and on. The behavior…

While driving, my brake pedal would randomly lose power assist. The pedal would get hard and I couldn't press it down normally, and I had to push as hard as I could just to get the car to slow down. This happened more than once while driving and I almost crashed because I couldn't stop the car in time. A scan later showed codes C1252 (brake booster pump motor on-time abnormally long), C1253 (pump motor relay fault), and C1256 (accumulator pressure low), pointing to a failure in the brake…

The low-beam headlight bulbs on my 2010 Toyota Prius keep burning out, about every [6 months or less]. Since I have owned the vehicle I have replaced them too many times to count, on both sides, but twice as often on the drivers side. The most recent failure was on XXX, my driver low beam failed while I was driving at night on a county highway in heavy rain. Visibility was already poor, and I was stopped by law enforcement because of the burned-out headlight. I was given a warning to get it…
